Stretch Code Help Lawrence MA - Quick Facts
Local energy code in Lawrence
- Lawrence enforces the Massachusetts Stretch Energy Code for new construction and major renovations. IECC Climate Zone 5A.
- Massachusetts has three energy-code levels - base (2021 IECC), Stretch, and Specialized (Opt-In) - and Lawrence is on the Stretch Code.
What your project must hit in Lawrence
- A HERS rating is required in Lawrence for: new construction; additions over 1,000 sq ft (or greater than 100% of the existing conditioned floor area); and extensive Level 3 alterations over 1,000 sq ft affecting more than 50% of the conditioned floor area.
- New home, mixed-fuel (gas heat, hot water or cooking): must reach HERS 42 or lower.
- New home, all-electric: must reach HERS 45 or lower.
- Embodied-carbon materials credit: allows up to HERS 48.
- ADU, mixed-fuel (gas): HERS 52; ADU, all-electric: HERS 55; ADU with the embodied-carbon credit: HERS 58.
- Major additions and renovations: HERS 65 (mixed-fuel) or HERS 70 (all-electric).
- Air tightness: a blower door test at 3.0 ACH50 or tighter; duct leakage capped at 4.0 CFM25 per 100 sq ft total leakage (8.0 when all ducts are inside conditioned space - the test is still required).
- Also required in new homes: whole-house mechanical ventilation (ASHRAE 62.2) and EV-ready wiring; compliance runs through the HERS / Energy Rating Index path (2025 code section R406).
How compliance is verified
- Energy model from your plans, a pre-drywall (rough) inspection, blower door and duct leakage testing, then a final HERS certificate filed with the Lawrence building department.
- Same-day preliminary HERS reports; blower door and duct results in 24-48 hours, with fail-fix guidance if a home misses the target.

Energy Code Path for Lawrence Projects
The state's municipal adoption list shows Lawrence on the Stretch Code, effective January 1, 2018; it has not adopted the Specialized (Opt-In) Code.
Here is what that means in practice for a Lawrence project:
- New homes. HERS 42 for mixed-fuel homes, HERS 45 for all-electric homes, or certification through Passive House.
- Large additions and renovations. Projects adding over 1,000 sq ft or more than 100% of the existing home need HERS 65 (mixed-fuel) or HERS 70 (all-electric).
- Smaller additions and alterations. REScheck or the prescriptive path is usually enough.
- Commercial. COMcheck works for commercial buildings up to 20,000 sq ft.
In practice, the HERS number is earned twice for a Lawrence project: once on paper, when we model the plans for the permit, and again in the field, when the blower door and duct leakage tests confirm the house was built tight. Pre-drywall inspections keep surprises out of that final test.
Fuel choice matters early: an all-electric design with heat pumps moves the target from HERS 42 to 45 (or 65 to 70 on a large renovation), which can save money on insulation or windows.
In Lawrence, permits are handled by the Inspectional Services Department. The city takes applications and payments through its online Citizenserve permit system.
Lawrence is on the state's Section 3A compliant list. New multifamily projects under that zoning still have to meet the energy code targets above.
HEEC serves Lawrence from our Everett office at 371 Main St, handling HERS ratings, blower door testing, and REScheck or COMcheck reports.
